seachnasaigh - again thanks for all of this and please no rush especially given you've got machine woes. Really just a couple of quick Q's and some thoughts... When you say .."each test render takes a while"..how long would you say each one takes? In your description of how it works, would be I correct - or not :)- in saying if there was only 1 "neon" tube, that could be used to light a scene? Obviously they'd be no glow, but it would it still need a IDL emitter? Whats the difference twxit P8 and P9 emitters? In your second image with the mirror I see you - rightly - caution about placing a mirror behind it. Not sure here but I wonder if a possible the solution might be to place a flattened version of the emitter behind the IDL emitter. Kinda like how I taped black card behind the eyeglass light and the mouth to stop light from spilling out from behind the mask and mouth. Or would that cause the same effect as in real life. Noticed on the real one at times I'd get some lens flare. Yea I know cliched, but did look rather cool :) Annoyingly as my SLR has an annoying sensor dust-spot, at certain angles I was getting some odd spots so that didn't work, but could lens flares be possible in poser? BTW sorry to read you've have to rebuild part of your mega-machine. Looks like an amazingly powerful piece of kit, the cooling system alone says don't mess with me!

Pinky - you left the lens cap of your mind on again.
